We thought it was very good and quite informative, but too often it veered into 'schools programme trying to be cool & exciting' territory. Why three presenters? And please - why is it now considered de rigeur to have presenters carrying mugs around with them?

I don'd mind the mugs but what I find annoying is the recent trend for presenters to control what's being displayed on a screen by swiping an iPad. There's no need for it, it just says "hey, look, I have an iPad". Sky News are the worst for it but it has started to creep into other programmes.
